摘要
优质低度白酒是我国白酒产业的发展方向。采用多种定量分析方法连用的策略系统分析比较了主流浓香型白酒企业生产的7组同系列优质低度(乙醇体积分数低于42%)和高度(乙醇体积分数为52%)浓香型白酒挥发性风味组分差异特征。比较分析结果显示,在定量分析的83种挥发性风味中,同系列酒样中高度白酒含量高于低度白酒含量的挥发性风味组分有32种,主要包括20种酯,3种醇,2种酸,4种醛酮等,这些化合物大多是白酒的骨架成分。同系列酒样中低度白酒含量高于高度白酒的挥发性风味组分有32种,主要包括5种有机酸类风味化合物,9种酯,6种醇,8种醛酮,2种呋喃,1种硫化物和1种萜烯。这些风味物质多是白酒中含量较低,但风味阈值也较低的“量微香大”风味化合物。研究结果显示,优质低度白酒中微量风味组分的种类和含量均较为丰富,浓香型白酒中“量微香大”风味化合物可能是调节低度白酒风味品质的重要因素。
High-quality and low-alcohol liquor is the direction of Chinese liquor industry development.A variety of quantitative analysis methods were employed to analyze and compare the volatile compounds of 7 groups of high-quality low-alcohol(<42%vol)and high-alcohol(52%vol)strong-aroma type of Baijiu(Chinese liquor)produced by mainstream strong-aroma type of Baijiu companies systematically.A total of 83 volatile compounds were quantitated.The contents of 32 compounds in high-alcohol strong-aroma type of Baijiu were higher than that of low-alcohol from the same series including 20 esters,3 alcohols,2 acids,4 aldehydes&ketones and 3 phenols.While the contents of another 32 compounds in low-alcohol strong-aroma type of Baijiu were higher than that of high-alcohol from the same series which includes 5 organic acid flavor compounds,9 esters,6 alcohols,8 aldehydes and ketones,2 furans,1 sulfide and 1 terpene.Most of these flavor substances were flavor compounds at trace level and with even lower odor thresholds.The results indicated that the types and concentrations of trace flavor components in high-quality and low-alcohol liquor were rich,and the flavor compounds which had great aroma contributions with low concentrations in strong-aroma type of Baijiu might be a significant factor in regulating the flavor quality of low-alcohol liquor.
